Low Concrete Block Wall Foundation

[Antscran]

Hi,

I am looking to build a small garden wall using a standard dense block (215mm*4400mm*100mm), they will be laid 215mm face 5 high so the wall will be around 400mm-500mm high, length is approximately 2.5m.

The underlying soil is pretty stable and not been disturbed for a long time, the blocks can sit centrally on the foundation, what should I aim for with regards the concrete foundation dimensions?

Thanks,
Ant

500 wide by 300mm deep (formation level ~450mm below ground level) is the standard landscaping BRE design.

Thank you very much will use this, would this also be written down anywhere officially?
